To aZZ whom it may concern.

. Be it known that I", CLARENCE BARNES, residin at Stillwater, in the county of Payne and tate of Oklahoma, a citizen of the United States, have invented certain new and useful Improvements in Condensers for Automobile Radiators, of which the followin is a specification.

y invention relates to condensers f0 automobile radiators, and I is especially adapted for use when using an anti-freezing mixture.

It has been found thatv most of the antifreeze mixtures boil or vaporize at a comparatively low temperature, and that the temperature of an engine, even in cold weather is entirely too hot for the antifreeze mixture, especially alcohol. There fore the mixture is continually vaporized and passes out through the overflow and is wasted.

The object of my invention is to arrange a condenser to the radiator-cap which will be exposed to cold air, in order that the vapor arising from the radiator may be condensed and returned to the radiator.

A further object is to provide a vent in the condenser which will permit the excess vapor which has not been condensed by passing through the condenser to pass ofi before reachin the radiator.

A still further object is to provide a valve at the lower end of the condenser outlet,

whereby the vapors may flow in one direction to the condenser eliminating the possibility of the vapors being vented from the radiator before passing through the condenser coil. I

In the accom anying drawings:

Fig. 1 is a ront view of the radiatnpartly in section showing the attachment applied;

ig. 2 is a top plan view thereof.

The numeral 1 indicates the radiator; 52, the neck or dome; and 3, the cap therefor. 4, indicates the usual venting tube, which, as shown, is closed by a suitable plug 5 when the condenser is in use. ihe condenser preferably consists of a spirally coiled tubing 6, the intake end? thereof being received in an opening 8 in the radiator cap 2. This tubing 6 preferablyextends verticall from the cap to a given height. when it is-bentin a spir'al'form as at 9, leading downwardly;

e outlet end 10 thereof passes through a centralopening 11 in the radiator-cap, and

well down into the neck 2 of the radiator, preferably being provided'at the outlet end with a flat valve 12 which prevents the p0ssibility of the vapors arising from the contents of the radiator and passing only in one direction through the condenser.

Arranged at the lower end of the spiral portion of the condenser is a vent tube 13, which extends vertically from the condenser to a height slightly above the condenser to permit excess vapor to pass off before reach-. ing the radiator.

In operation, assuming the condenser to be applied to the radiator of an automobile, and the usual vent in the radiator plugged up, should the contents of the radiator rise to a boilin oint, the steam or vapors generated woudd rise into the coil 9 of the con denser through the condenser inlet 8, and be cooled therein, drained back into the radiator, into the condenser outlet 10 and pass into the radiator in the form of liquid,

Should the .volume of escaping steam or vapors be so great as not to entirely condense before reaching the lower portion of the condenser, such vapors would pass oii through the bent pipe 13, thereby relieving the radiator and condenser of any undue internal ressure.

ltwl thus be seen that I have arranged a condenser which is adapted to any form of radiator, and one which is simple and effective in operation.

I claim:

1. In combination, an auto radiator cap, a condenser carried thereby, consisting of a spirally-wound coil having its upper end projecting downwardly and connected through the cap and in communication with the radiator forming the inlet end of the condenser, the lower outlet end of said condenser passing through the radiator cap and in communication with the radiator. and being provided with an automatic outlet valve, and a vent connected to said condenser coil adjacent the outlet end thereof.

2. The combination with a radiator having a water overflow pipe, of means for closing the overflow pipe, a cap for said radiator, a condenser carried thereby consisting of a spirally-wound coil vlng its upper end projecting downwardly and connected through the cap and in communication with the radiator to form the inlet and of the condenser, the lower end of said condenser passing through the radiator cap and being in communication with the radiator and provided with an automatic valve, and a vent connected to the lower portion of said condenser coil and extending vertically above the condenser.

3. In combination, an auto radiator cap, a condenser carried thereby, consisting of a spirally wound coil having its upper end projecting downwardly and connected with the cap and in communication with the radiator forming the inlet of the condenser,

the lower outlet end of said condenser passing through the radiator cap and in communication with the radiator, a vent connected adjacent the outlet end of the condenser and projecting above the uppermost coil and a one-way valve connected to the outlet end of the condenser.

In testimony whereof I hereunto aflix my signature.
